Sorry I've been quiet the last few days. Typed up half a post then lost everything cuz accidental click >_> Then I had a slight infection so more drugs. Life is rubbing lemon in my face right now...
Maybe you'll just need to implement a number of days per round that posts need to be put in or that person's character is just skipped. In other words, a round lasts let's say three days. The players need to send in their posts during that timeframe or their character doesn't appear during that round. If a player misses too many rounds, then unless they have valid reasons, then that player has probably lost interest and might just need to be taken off. It works well on RWBY AU: Heroes of a Different Story.
But 4 ppl have already posted bro. I'd say you clearly have more than one active player.
(Even so, I hate deadlines... pls no deadlines...)
Jays wants to join, but he's got serious stuff going on. Simj, idk, maybe something came up for him. I think it's best to keep moving if you're feeling antsy, Laue.
